Program & Bank Changes
When the MIDI standard was first established, it enabled the user to access only 128 different sounds using program change messages

The language MIDI uses to communicate between musical instruments only allows for program change commands
“0” = 128 programs total). Because of inherent limitations of the MIDI communication protocol, the number of directly accessible programs (using program change messages) cannot easily be expanded beyond 128. Thus, a system of banks, with 128 sounds in each, has been created that enables manufacturers to overcome the
128 Banks with 128 sounds in each bank is the basic principle used to expand the number of accessible sounds. However, to avoid reaching the new limit of the resulting 16,384 possible sounds (128 banks x 128 programs) accessible using a bank change combined with a program change, another layer of banks was added. The result is a system of 128 banks that can contain 128 sub- banks in each of them, which, in turn, can contain 128 sounds (programs) within them.Bank change messages are useful when calling up sounds from a large library that may exist in a particular sound module or software synth. For example devices that are built with Roland’s GS specification or Yamaha’s XG specification require you to specify
